if single cam harness should work for a twin cam cluster...why isn't my twin cam cluster speedo and rpm ain't working? that's my concern.

let me tell you what...when I purchase the twin cam cluster it already have a harness on it so all i did was just swapped out all the small bulbs from my single cam to the twin cam....

so for sure, i know that my orignal harness from the single cam should work...i'm just curious that the harness that is on the twin cam might be bad harness...that my case....so in the morning i will put my previous harness and swapped into the twin cam one...

so, hopefully that it...hopefully....and so i will keep up the update if something else goes wrong....

and EPSTEIN thanks dude...i would be boiling water by now....
